Two older instructors are sitting around
the department lounge, talking about how much they love to teach, but hate giving
exams. ``In heaven, I bet they have no exams!" says one of them. ``All the
students would come to class prepared, but there
would be no exams to give and grade." ``What a place," says the second. ``Hey,
let's make a pact. Whoever dies first comes back and tells the other what
it's like to teach calculus in heaven." ``Sounds good," says the first. A
week later the first instructor slips on a discarded pocket protector and leaves
this world. That night, while the second instructor is sleeping, the first one
comes to visit him in a dream. ``So, what's it like?" asks the second. ``Well, I
have good news and bad news," says the first. ``The good news is that there is
calculus teaching in heaven, and I have to tell you, the students are fantastic.
Enthusiastic. Attentive. It's a dream come true. And no exams whatsoever! They
don't call it heaven for nothing." ``Wow, that sounds great," says the second.
``What's the bad news?"
The first shrugs. ``You're teaching on Monday."

As the time for the exam approaches, it is likely
that your instructor will realize that some key topic
that should appear on the exam was never discussed in class. So drink coffee,
stick a tack in your shoe, do whatever it takes
